This application is a Section 371 of International Application No. PCT/CN2018/071562, filed Jan. 5, 2018, which was published in the English language on Jul. 12, 2018 under International Publication No. WO 2018/127130 A1, which claims priority under to U.S. Provisional Patent Application No. 62/443,660, filed Jan. 7, 2017, and the disclosures of which are incorporated herein by reference.

FIELD OF THE INVENTION

Provided are certain compounds or pharmaceutically acceptable salts thereof which can inhibit anti-apoptotic Bcl-2 family proteins and may be useful for the treatment of hyper-proliferative diseases like cancer and inflammation, or immune and autoimmune diseases.

BACKGROUND OF THE INVENTION

Hyper-proliferative diseases like cancer and inflammation are attracting the scientific community to provide therapeutic benefits. In this regard efforts have been made to identify and target specific mechanisms which play a role in proliferating the diseases.

Protein-protein interactions (PPIs) control many biological process, such as cell proliferation, growth, differentiation, signal transduction and apoptosis. Abnormal regulation of PPIs leads to different diseases. Thus, PPIs represent an important class of molecular targets for novel human therapeutics.

The B-cell lymphoma-2 (Bcl-2) family of proteins is central to the regulation of apoptosis, which is vital for proper tissue development and cellular homeostasis. Apoptosis occurs via activation of two different pathways. The extrinsic pathway, triggered by activation of the intrinsic pathway involving members of the Bcl-2 family of proteins. The Bcl-2 family protein includes anti-apoptotic proteins, such as Bcl-2, Bcl-XL and Mcl-1, and pro-apoptotic proteins, including Bid, Bim, Bad, Bak and Bax.

Anti-apoptotic Bcl-2 family members are often found to be up-regulated in cancers and are associated with stage of disease and prognosis. Therefore, Bcl-2 proteins are under investigation as potential therapeutic drug targets which include, for example, Bcl-2 and Bcl-XL. Expression of Bcl-2 proteins is an independent indicator of poor prognosis in tumors including chronic lymphocytic leukemia (CLL), prostate cancer, and small cell lung cancer (SCLC). In other tumors such as colorectal cancer, Bcl-X_(L) expression is linked to grade and stage, and in hepatocellular cancer, Bcl-XL expression is an independent marker of poorer overall and disease-free survival.

Therefore, a compound having an inhibitory activity on Bcl-2 will be useful for the prevention or treatment of cancer. In this regard, a novel class of Bcl-2 inhibitors is provided herein. Although Bcl-2 inhibitors were disclosed in the arts, many suffer from having short half-life or toxicity. Therefore, there is a need for new Bcl-2 inhibitors that have at least one advantageous property selected from potency, stability, selectivity, toxicity, pharmacodynamic and pharmacokinetic properties as an alternative for the treatment of hyper-proliferative diseases. In this regard, a novel class of Bcl-2 inhibitors is provided herein.

In cases where the aryl substituent is bicyclic or tricyclic and at least one ring is non-aromatic, it is understood that attachment is via the aromatic ring.

For example, aryl includes 5- and 6-membered carbocyclic aromatic rings fused to a 5- to 7-membered heterocyclic ring containing one or more heteroatoms selected from N, O, and S, provided that the point of attachment is at the carbocyclic aromatic ring. Bivalent radicals formed from substituted benzene derivatives and having the free valences at ring atoms are named as substituted phenylene radicals. Bivalent radicals derived from univalent polycyclic hydrocarbon radicals whose names end in “-yl” by removal of one hydrogen atom from the carbon atom with the free valence are named by adding “-idene” to the name of the corresponding univalent radical, e.g., a naphthyl group with two points of attachment is termed naphthylidene. Aryl, however, does not encompass or overlap in any way with heteroaryl, separately defined below. Hence, if one or more carbocyclic aromatic rings are fused with a heterocyclic aromatic ring, the resulting ring system is heteroaryl, not aryl, as defined herein.

The term “heteroaryl”, employed alone or in combination with other terms, refers to

-   -   5- to 8-membered aromatic, monocyclic rings containing one or         more, for example, from 1 to 4, or, in some embodiments, from 1         to 3, heteroatoms selected from N, O and S, with the remaining         ring atoms being carbon;     -   8- to 12-membered bicyclic rings containing one or more, for         example, from 1 to 4, or, in some embodiments, from 1 to 3,         heteroatoms selected from N, O and S, with the remaining ring         atoms being carbon and wherein at least one heteroatom is         present in an aromatic ring; and     -   11- to 14-membered tricyclic rings containing one or more, for         example, from 1 to 4, or in some embodiments, from 1 to 3,         heteroatoms selected from N, O and S, with the remaining ring         atoms being carbon and wherein at least one heteroatom is         present in an aromatic ring.

When the total number of S and O atoms in the heteroaryl group exceeds 1, those heteroatoms are not adjacent to one another. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 2. In some embodiments, the total number of S and O atoms in the aromatic heterocycle is not more than 1.

Further heteroaryl groups include but are not limited to pyrrolyl, isothiazolyl, triazinyl, pyrazinyl, pyridazinyl, indolyl, benzotriazolyl, quinoxalinyl and isoquinolinyl. As with the definition of heterocycle below, “heteroaryl” is also understood to include the N-oxide derivative of any nitrogen-containing heteroaryl.

Bivalent radicals derived from univalent heteroaryl radicals whose names end in “-yl” by removal of one hydrogen atom from the atom with the free valence are named by adding “-idene” to the name of the corresponding univalent radical, e.g., a pyridyl group with two points of attachment is a pyridylidene. Heteroaryl does not encompass or overlap with aryl as defined above.

In cases where the heteroaryl substituent is bicyclic or tricyclic and at least one ring is non-aromatic or contains no heteroatoms, it is understood that attachment is via the aromatic ring or via the heteroatom containing ring, respectively.

The term “heterocycle”, employed alone or in combination with other terms, (and variations thereof such as “heterocyclic”, or “heterocyclyl”) broadly refers to a single aliphatic ring, usually with 3 to 12 ring atoms, containing at least 2 carbon atoms in addition to one or more, preferably one to three heteroatoms independently selected from oxygen, sulfur, nitrogen and phosphorus as well as combinations comprising at least one of the foregoing heteroatoms. Alternatively , a heterocycle as defined above may be multicyclic ring system (e.g. bicyclic) in which two or more rings may be fused or bridged or spiro together, wherein at least one such ring contains one or more heteroatoms independently selected from oxygen, sulfur, nitrogen and phosphorus. “Heterocycle” also refers to 5- to 7-membered heterocyclic ring containing one or more heteroatoms selected from oxygen, sulfur, nitrogen and phosphorus fused with 5- and 6-membered carbocyclic aromatic ring, provided that the point of attachment is at the heterocyclic ring. The rings may be saturated or have one or more double bonds (i.e. partially unsaturated). The heterocycle can be substituted by oxo. The point of the attachment may be carbon or heteroatom in the heterocyclic ring, provided that attachment results in the creation of a stable structure. When the heterocyclic ring has substituents, it is understood that the substituents may be attached to any atom in the ring, whether a heteroatom or a carbon atom, provided that a stable chemical structure results. Heterocycle does not overlap with heteroaryl.

Suitable heterocycles include, for example (as numbered from the linkage position assigned priority 1), 1-pyrrolidinyl, 2-pyrrolidinyl, 2,4-imidazolidinyl, 2,3-pyrazolidinyl, 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-piperidinyl, 2,5-piperazinyl. 1,4-piperazinyl and 2,3-pyridazinyl. Morpholinyl groups are also contemplated, including 2-morpholinyl and 3-morpholinyl (numbered wherein the oxygen is assigned priority 1). Substituted heterocycle also includes ring systems substituted with one or more oxo moieties, such as piperidinyl N-oxide, morpholinyl-N-oxide, 1-oxo-1-thiomorpholinyl and 1,1-dioxo-1-thiomorpholinyl. Bicyclic heterocycles include, for example:

When used in the phrase “C₃₋₁₀ cycloalkyl-C₁₋₄ alkyl”, the term “C₃₋₁₀” refers to the cycloalkyl portion of the moiety and does not describe the number of atoms in the alkyl portion of the moiety, and the term “C₁₋₄” refers to the alkyl portion of the moiety and does not describe the number of atoms in the cycloalkyl portion of the moiety.

As used herein, “heteroaryl-alkyl” refers to alkyl substituted by heteroaryl. When used in the phrase “heteroaryl-C₁₋₄ alkyl”, the term “C₁₋₄” refers to the alkyl portion of the moiety and does not describe the number of atoms in the heteroaryl portion of the moiety.

For avoidance of doubt, reference, for example, to substitution of alkyl, cycloalkyl, heterocyclyl, aryl and/or heteroaryl refers to substitution of each of those groups individually as well as to substitutions of combinations of those groups. That is, if R¹ is aryl-C₁₋₄ alkyl, the aryl portion may be unsubstituted or substituted with at least one substituent, such as one, two, three, or four substituents, independently selected from R^(X) and the alkyl portion may also be unsubstituted or substituted with at least one substituent, such as one, two, three, or four substituens, independently selected from R^(X).

Isotope Enriched or Labeled Compounds.

Compounds of the invention can exist in isotope-labeled or -enriched form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes can be radioactive or non-radioactive isotopes. Isotopes of atoms such as hydrogen, carbon, nitrogen, phosphorous, sulfur, fluorine, chlorine and iodine include, but are not limited to, ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ³²P, ³⁵S, ¹⁸F, ³⁶Cl and ¹²⁵I. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention.

In another embodiment, the isotope-labeled compounds contain deuterium (²H), tritium (³H) or ¹⁴C isotopes. Isotope-labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotope-labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples disclosed herein and Schemes by substituting a readily available isotope-labeled reagent for a non-labeled reagent. In some instances, compounds may be treated with isotope-labeled reagents to exchange a normal atom with its isotope, for example, hydrogen for deuterium can be exchanged by the action of a deuterated acid such as D₂SO₄/D₂O. In addition to the above, relevant procedures and intermediates are disclosed, for instance, in Lizondo, J et al, Drugs Fut, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al, Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat.

The isotope-labeled compounds of the invention may be used as standards to determine the effectiveness of Bcl-2 inhibitors in binding assays. Isotope containing compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the nonisotope-labeled parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al, J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol, 77, 79-88 (1999).

In addition, non-radio active isotope containing drugs, such as deuterated drugs called “heavy drugs” can be used for the treatment of diseases and conditions related to Bcl-2 activity. Increasing the amount of an isotope present in a compound above its natural abundance is called enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. Replacement of up to about 15% of normal atom with a heavy isotope has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. New York Acad. Sci 1960 84: 736; Czakja D M et al., Am. J. Physiol. 1961 201: 357). Acute replacement of as high as 15%-23% in human fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).

Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one important exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. Accordingly, the incorporation of an isotope at a site of metabolism or enzymatic transformation will slow said reactions potentially altering the pharmacokinetic profile or efficacy relative to the non-isotopic compound.

EXAMPLES

Various methods may be developed for synthesizing a compound of formula (I) or a pharmaceutically acceptable salt thereof. Representative methods for synthesizing a compound of formula (I) or a pharmaceutically acceptable salt thereof are provided in the Examples. It is noted, however, that a compound of formula (I) or a pharmaceutically acceptable salt thereof may also be synthesized by other synthetic routes that others may devise.

It will be readily recognized that certain compounds of formula (I) have atoms with linkages to other atoms that confer a particular stereochemistry to the compound (e.g., chiral centers). It is recognized that synthesis of a compound of formula (I) or a pharmaceutically acceptable salt thereof may result in the creation of mixtures of different stereoisomers (enantiomers, diastereomers). Unless a particular stereochemistry is specified, recitation of a compound is intended to encompass all of the different possible stereoisomers.

Ae compound of formula (I) can also be prepared as a pharmaceutically acceptable acid addition salt by, for example, reacting the free base form of the at least one compound with a pharmaceutically acceptable inorganic or organic acid. Alternatively, a pharmaceutically acceptable base addition salt of the at least one compound of formula (I) can be prepared by, for example, reacting the free acid form of the at least one compound with a pharmaceutically acceptable inorganic or organic base. Inorganic and organic acids and bases suitable for the preparation of the pharmaceutically acceptable salts of compounds of formula (I) are set forth in the definitions section of this Application. Alternatively, the salt forms of the compounds of formula (I) can be prepared using salts of the starting materials or intermediates.

Alternatively, the N-oxides of the compounds of formula (I) can be prepared from the N-oxide of an appropriate starting material.

Compounds of formula (I) in an unoxidized form can be prepared from N-oxides of compounds of formula (I) by, for example, treating with a reducing agent (e.g., sulfur, sulfur dioxide, triphenyl phosphine, lithium borohydride, sodium borohydride, phosphorus trichloride, tribromide, and the like) in an suitable inert organic solvent (e.g., acetonitrile, ethanol, aqueous dioxane, and the like) at 0 to 80° C.

Protected derivatives of the compounds of formula (I) can be made by methods known to those of ordinary skill in the art.

Synthetic Schemes

A compound of formula I or a pharmaceutically acceptable salt thereof may be synthesized according to a variety of reaction schemes. Some illustrative schemes are provided below and in the examples. Other reaction schemes could be readily devised by those skilled in the art in view of the present disclosure.

In the reactions described hereinafter it may be necessary to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups may be used in accordance with standard practice, for examples see T. W. Greene and P. G. M. Wuts in “Protective Groups in Organic Chemistry” John Wiley and Sons, 1991.

Synthetic methods for preparing the compounds of the present invention are illustrated in the following Schemes and Examples. Starting materials are commercially available or may be made according to procedures known in the art or as illustrated herein.

As an illustration, one of the approaches to the synthesis of compounds of formula I is shown in Scheme 1. Compounds of formula I can be easily assembled from sulfonamides or imino substituted sulfonamides of formula III with acids of formula II via cross coupling reactions such as peptide forming conditions known in the literature. Furthermore, compounds of formula II and III are readily accessible through methods known in the art.

As an illustration of compounds of formula III, one of the synthetic approach to the compounds of formula IIIA is outlined in Scheme 2. As shown in the scheme, the compound of formula IIIA can be prepared from IIIA-a via a sequence of manipulations. Cyclic phosphine oxide of formula IIIA-f with atom A as nitrogen can be prepared from the double Michael addition of amine IIIA-b to divinylphosphine oxide IIIA-a followed by deprotection of protecting group on nitrogen and introduction of Rb when necessary. Similarly, cyclic phosphine oxide of formula IIIA-f with atom A as carbon can be prepared by reacting beta cyano ester IIIA-c with IIIA-a followed by decarboxylation of the ester group and conversion of the cyano group into amine and installment of Rb onto the resulting nitrogen when needed. Coupling of IIIA-f with IV in the presence of base provides IIIA via nucleophilic displacement of the halide on the aromatic ring of IV by the amine group in compounds of formula IIIA-f.

One synthetic route of compounds of formula IIIB is shown in Scheme 3. Starting from readily available compound amine IIIB-f is produced through a sequence of oxidative amination, oxidation, cleavage of the cyano group on the imino group, installment of Rc on the imino group and deprotection of the protecting group on nitrogen and coupling of the nitrogen containg fragment when needed. IIIB was prepared from IIIB-f and IV under the similar conditions to the preparation of IIIA shown in Scheme 2.

As a further illustration of compounds of formula III, the synthesis of compounds of formula IIIC is provided in Scheme 4. Reaction of sulfoximine IIIC-b with cycloketone IIIC-a provides compounds of formula IIIC-c. IIIC can be prepared from IIIC-c following the similar manipulations described in the preparation of IIIB.

In some cases the order of carrying out the foregoing reaction schemes may be varied to facilitate the reaction or to avoid unwanted reaction products. The following examples are provided so that the invention might be more fully understood. These examples are illustrative only and should not be construed as limiting the invention in any way.

Cell Proliferation Assays

MTS testing kit was purchased from Promega. The RPMI-1640, Fetal bovine serum and Penicillin-Streptomycin were purchased from Gibco. Dimethyl sulfoxide (DMSO) was purchased from Sigma.

To investigate whether a compound is able to inhibit the activity of Bcl-2 in cells, a mechanism-based assay using DOHH2 (DSMZ No.® ACC 47) and RS4;11 (ATCC® CRL-1873™) cell was developed. In this assay, inhibition of Bcl-2 was detected by the inhibition of DOHH2 and RS4;11 cells proliferation. DOHH2 and RS4;11 cells were cultured in culture flasks to 40-80% confluence in RPMI-1640 plus 10% fetal bovine serum. Cells were collected and plated onto 96-well plates at desired cell density (DOHH2: 5000 cells/well; RS4;11: 30000 cells/well). Plates were incubated overnight at 37° C., with 5% CO₂ to adhere. Compounds were added to the plates, and the final compound concentrations were 10000, 3333, 1111, 270, 124, 41, 14, 4.6 and 1.5 nM. Plates plated with DOHH2 or RS4;11 cells were placed at 37° C., with 5% CO₂ for 120 h (DOHH2) or 72 h (RS4;11) respectively. 20 μl MTS/100 μl medium mixture solution were added to each well and incubate the plates for exactly 2 hours. The reaction was stopped by adding 25 μl 10% SDS per well. Measure absorbance at 490 nm and 650 nm (reference wavelength). ICso was calculated using GraphPad Prism 5.0.

Select compounds prepared as described above were assayed according to the biological procedures described herein. The results are given in the table 2.
